Omental abscess due to a spilled gallstone after laparoscopic cholecystectomy

Lost gallstones during laparoscopic cholecystectomy as a common but underestimated complication-case report and review of the literature

Introduction

Laparoscopic cholecystectomy (LC) represents one of the most commonly performed routine abdominal surgeries. Nevertheless, besides bile duct injury, problems caused by lost gallstones represent a heavily underestimated and underreported possible late complication after LC.

Methods

Case report of a Clavien-Dindo IVb complication after supposedly straightforward LC and review of all published case reports on complications from lost gallstones from 2000-2022.

Case Report

An 86-year-old patient developed a perihepatic abscess due to lost gallstones 6 months after LC. The patient had to undergo open surgery to successfully drain the abscess. Reactive pleural effusion needed additional drainage. Postoperative ICU stay was 13 days. The patient was finally discharged after 33 days on a geriatric remobilization ward and died 12 months later due to acute cardiac decompensation.

Conclusion

Intraabdominal abscess formation due to spilled gallstones may present years after LC as a late complication. Surgical management in order to completely evacuate the abscess and remove all spilled gallstones may be required, which could be associated with high morbidity and mortality, especially in elderly patients. Regarding the overt underreporting of gallstone spillage in case of postoperative gallstone-related complications, focus need be put on precise reporting of even apparently innocuous complications during LC.

Effects of fast-track recovery programme on the surgical site wound infection in patients undergoing biliary stones surgery: A meta-analysis

To systematically evaluate the effects of a fast-track recovery programme on perioperative wound infections and postoperative complications in patients undergoing biliary tone surgery, we conducted a comprehensive search of PubMed, Web of Science, Cochrane Library, Embase, China Biomedical Literature Database, Wanfang and China National Knowledge Infrastructure databases from inception to 29 September 2023 for randomised controlled trials (RCTs) focusing on the application of a fast-track recovery programme in patients undergoing biliary stone surgery. Two researchers independently screened and evaluated the studies based on predefined inclusion and exclusion criteria, and data were subsequently extracted from the included studies. Stata software (version 17.0) was employed for data analysis. Overall, 19 RCTs involving 2363 patients were included, with 1178 patients allocated to the fast-track recovery programme group and 1185 to the conventional care group. The results revealed a significantly lower occurrence of wound infection (3.74% vs. 9.45%, OR = 0.36, 95% CI: 0.25-0.51, p < 0.001) and postoperative complications (11.38% vs. 27.34%, OR = 0.31, 95% CI: 0.25-0.39, p < 0.001) in the fast-track recovery programme group compared to the conventional care group. The available evidence supports the assertion that implementing a fast-track recovery programme in the perioperative period of patients undergoing biliary stone surgery effectively reduces the incidence of wound infections and postoperative complications while facilitating postoperative recovery.

[Minimally invasive interventions for complications associated with intra-abdominal calculi after laparoscopic cholecystectomy]

OBJECTIVE

To study the possibilities of minimally invasive methods for removing intra-abdominal calculi after laparoscopic cholecystectomy.

MATERIAL AND METHODS

There were 5 patients with abdominal abscesses associated with infected calculi after previous laparoscopic cholecystectomy at the Sklifosovsky Research Institute for Emergency Care between 2020 and 2023. Mean age of patients was 55±12 years. There were 3 (60%) women and 2 (40%) men. All patients underwent minimally invasive treatment.

RESULTS

Four patients (80%) underwent percutaneous drainage of abscess with subsequent replacement by larger drains and removal of calculi with endoscopic assistance. Event-free period after cholecystectomy was 44±32 months. One patient developed subhepatic abscess in 72 months after laparoscopic cholecystectomy. This patient underwent transluminal removal of calculus through the duodenal wall. There was 1 calculus in 3 (60%) patients, 2 calculi in 1 (20%) patient and 3 calculi in 1 (20%) patient.

CONCLUSION

The above-mentioned cases demonstrate successful minimally invasive interventions for symptomatic abdominal calculi after laparoscopic cholecystectomy. Minimally invasive treatment can reduce surgical aggression and accelerate rehabilitation.

Dropped gallstone-related perihepatic abscess 20 years after open cholecystectomy

INTRODUCTION

Gallstone spillage during cholecystectomy is a recognized complication that can lead to various postoperative complications.

CASE PRESENTATION

We present a rare case of a gallstone abscess that developed 20 years after an open cholecystectomy. An 80-year-old woman with a history of high blood pressure and previous gallbladder removal presented with severe abdominal pain. Imaging revealed a large abscess with a suspicious calcification, indicating a lost gallstone. Surgical intervention was performed, resulting in the removal of multiple gallstone fragments from the abscess cavity.

CLINICAL DISCUSSION

Gallbladder perforations and the spillage of gallstones are common complications during cholecystectomies, with laparoscopic procedures being more prone to stone spillage. Studies show a significant difference between open and laparoscopic cholecystectomies, with laparoscopy having a higher risk of spilled stones. Complications from spilled gallstones are rare but can vary in presentation and location. They may lead to long-term issues such as abscesses and even erosion into other organs. These complications can manifest years after surgery. Treatment involves evacuating the abscess and addressing the gallstone. Surgical intervention, like laparotomy or laparoscopy, is required for retrieval. Ensuring proper traction during surgery is crucial to prevent gallbladder perforation and stone spillage. Consideration of alternative, gentler instruments for traction may be beneficial.

CONCLUSION

Surgeons should be vigilant, proactive, and employ prophylactic measures to minimize complications related to gallstone spillage, ensuring the best possible patient outcomes.

CT and MR imaging of the greater omentum: Pictorial essay

The greater omentum is a unique anatomical structure that serves a critical function in the containment of inflammatory and infectious processes within the abdominal cavity. It is also a common site of involvement by metastases, as well as the primary location for various pathologic lesions of clinical significance. Its fibroadipose composition, large size, and position in the most anterior aspect of abdomen allow accurate visualization of the greater omentum on CT and MR images. Careful evaluation of the greater omentum can provide important clues to the diagnosis of the underlying abdominal disorder. The aim of this article is to present the normal appearance of the greater omentum, and the wide spectrum of its pathological features as demonstrated on CT and MRI of the abdomen.

Consequences of the spilled gallstones during laparoscopic cholecystectomy: a systematic review

INTRODUCTION

Complications secondary to spilled gallstones can be classified in the category of disease of medical progress because prior to advent of laparoscopic cholecystectomy very few reports published on the topic. The aim of the present study was to investigate the predisposing factors and the complication rate of spilled gallstones during laparoscopic cholecystectomy over the past 21 years.

METHODS

Embase, Pubmed, Medline, Google scholar and Cochrane library were systematically searched for pertinent literature.

RESULTS

Seventy five out of 181 articles were selected including 85 patients; of those 38% were men and 62% women. The median age of the cohort was 64 years old and ranged between 33 and 87 years. Only 23(27%) of the authors reported the incident of spillage of the gallstones during the operation. Time of onset of symptoms varied widely from the second postoperative day to 15 years later. Ten of 85 patients were asymptomatic and diagnosed with spilled gallstones incidentally. The rest of the patients presented with complications of severe morbidity and almost, 87% of the patients needed to be treated with surgical intervention and 12% with US ± CT scan guidance drainage. Only one perioperative death reported.

CONCLUSIONS

Symptomatic patients with lost gallstones present with severe morbidity complications and required mostly major surgical procedures. Therefore, standardisation of the management of spilled gallstones is needed urgently. Hospitals need to review their policy with audits and recommendations and clinical guidelines are needed urgently.

Update of the list of QPS-recommended microbiological agents intentionally added to food or feed as notified to EFSA 16: suitability of taxonomic units notified to EFSA until March 2022

The qualified presumption of safety (QPS) approach was developed to provide a regularly updated generic pre‐evaluation of the safety of microorganisms, intended for use in the food or feed chains, to support the work of EFSA's Scientific Panels. The QPS approach is based on an assessment of published data for each agent, with respect to its taxonomic identity, the body of relevant knowledge, safety concerns and occurrence of antimicrobial resistance. Safety concerns identified for a taxonomic unit (TU) are, where possible, confirmed at the species/strain or product level and reflected by ‘qualifications’. In the period covered by this statement, no new information was found that would change the status of previously recommended QPS TUs. Of the 50 microorganisms notified to EFSA in October 2021 to March 2022 (inclusive), 41 were not evaluated: 10 filamentous fungi, 1 Enterococcus faecium, 1 Clostridium butyricum, 3 Escherichia coli and 1 Streptomyces spp. because are excluded from QPS evaluation, and 25 TUs that have already a QPS status. Nine notifications, corresponding to seven TUs were evaluated: four of these, Streptococcus salivarius, Companilactobacillus formosensis, Pseudonocardia autotrophica and Papiliotrema terrestris, being evaluated for the first time. The other three, Microbacterium foliorum, Pseudomonas fluorescens and Ensifer adhaerens were re‐assessed. None of these TUs were recommended for QPS status: Ensifer adhaerens, Microbacterium foliorum, Companilactobacillus formosensis and Papiliotrema terrestris due to a limited body of knowledge, Streptococcus salivarius due to its ability to cause bacteraemia and systemic infection that results in a variety of morbidities, Pseudonocardia autotrophica due to lack of body of knowledge and uncertainty on the safety of biologically active compounds which can be produced, and Pseudomonas fluorescens due to possible safety concerns.

Spilled gallstones after laparoscopic cholecystectomy: a systematic review

&lt;b&gt; Aim: &lt;/b&gt; The study was conducted to analyse the recent peer-reviewed literature related to symptomatic spilled gallstones after Laparoscopic Cholecystectomy (LC). &lt;/br&gt;&lt;/br&gt; &lt;b&gt;Materials and methods:&lt;/b&gt; Articles published in the peer-reviewed journals of repute from 20122022 were evaluated for nine variables including: [I] age of the patient, [II] gender, [III] interval since index LC, [IV] index LC if emergent/difficult or elective/straightforward, [V] clinical presentation, [VI] spilled gallstones if detected by imaging, [VII] management, [VIII] approach to management, [IX] number of spilled gallstones. &lt;/br&gt;&lt;/br&gt; &lt;b&gt;Results:&lt;/b&gt; There were a total of 71 cases (37 males and 34 females) with a mean age of 63.7 years. The time of onset of symptoms from spilled gallstones, after index LC, ranged from 2 days to 15 years and 57 patients (80.3%) presented within 6 years. Forty (56.3%) patients were unaware of the fact that gallstone spillage had occurred during index LC. The retained gallstones were detected by imaging in 47 (66.1%) cases and they were multiple in 51 (71.8%). In 52 patients (73.2%), the stones manifested as abdominal abscess/foreign body granuloma; the other presentations being pelvic pain/fistula, intestinal obstruction, abdominal lump simulating malignancy, incidental finding of metastatic lesions and generalized peritonitis. The major approaches adopted to retrieve the retained stones included open surgery, laparoscopy and percutaneous drainage. There were two deaths (2.9%) due to spilled gallstones. &lt;/br&gt;&lt;/br&gt; &lt;b&gt;Conclusion:&lt;/b&gt; Retained gallstones represent a complication of laparoscopic cholecystectomy (LC) that has a potential to create morbidity and diagnostic difficulties, even after a substantial delay. There is a need to spread awareness about the adverse effects of spilled stones so that they are actively looked for and retrieved if gallbladder perforates during cholecystectomy. Whenever such a complication occurs, the patient should be properly informed and the details should be very clearly mentioned in the operation notes.

Is omentectomy necessary in the treatment of benign or malignant abdominal pathologies? A systematic review

BACKGROUND

The omentum is an organ that is easily sacrificed during abdominal surgery. The scope of omentectomy and whether a routine omentectomy should be performed are still unknown.

AIM

To review the literature in order to determine the physiological functions of the omentum and the roles it plays in pathological events in order to reveal the necessity for removal and preservation of the omentum.

METHODS

A clinical review of the English language literature based on the MEDLINE (PubMed) database was conducted using the keywords: “abdomen”, “gastrointestinal”, “tumor”, “inflammation”, “omental flap”, “metastasis”, “omentum”, and “omentectomy”. In addition, reports were also identified by systematically reviewing all references in retrieved papers.

RESULTS

The omentum functions as a natural barrier in areas where pathological processes occur in the abdominal cavity. The omentum limits and controls inflammatory and infectious pathologies that occur in the abdomen. It also aids in treatment due to its cellular functions including lymphatic drainage and phagocytosis. It shows similar behavior in tumors, but it cannot cope with increasing tumor burden. The stage of the disease changes due to the tumor mass it tries to control. Therefore, it is considered an indicator of poor prognosis. Due to this feature, the omentum is one of the first organs to be sacrificed during surgical procedures. However, there are many unknowns regarding the role and efficacy of the omentum in cancer.

CONCLUSION

The omentum is a unique organ that limits and controls inflammatory processes, foreign masses, and lesions that develop in the abdominal cavity. Omental flaps can be used in all anatomical areas, including the thorax, abdomen, pelvis, and extremities. The omentum is an organ that deserves the title of the abdominal policeman. It is generally accepted that the omentum should be removed in cases where there is tumor invasion. However, the positive or negative contribution of omental resection in the treatment of abdominal pathologies should be questioned.

Acute abdomen due to spilled gallstones: a diagnostic dilemma 10 years after laparoscopic cholecystectomy

Laparoscopic cholecystectomy (LC) carries a significant risk of gallbladder perforation and resulting scattering of bile stones into the abdominal cavity. The retrieval of the spilled stones is not always possible by laparoscopic technique. Most cases do not create long-term problems, although some cases may be complicated in future and create uncertainties regarding the correct diagnosis. Diagnosis can be difficult, and in most cases the patient may require open surgery for management of these complications. Herein, we report a case of acute abdomen due to spilled stones occurring 10 years after LC. In the first stage, definitive diagnosis could not be made with computed tomography examination. Finally, the patient was diagnosed with explorative laparotomy.
